Abstract (en)
[origin: EP0654593A2] An ignition timing control system for an internal combustion engine is associated with a fuel injection amount control system for calculating an amount of fuel to be supplied to the engine, based on operating conditions of the engine, correcting the calculated amount of fuel, based on an adherent amount of fuel adhering to the inner wall surface of the intake passage, and a carried-off amount of fuel to be carried off from the adherent fuel into each combustion chamber of the engine, and injecting the corrected fuel amount into the intake passage. The ignition timing control system comprises an ECU which detects whether the engine has been recovered from a fuel cut state to a fuel supply state, and calculates ignition timing of the engine, based on operating conditions of the engine detected by engine operating parameter sensors, including pressure within the intake passage. A retard amount by which the ignition timing is to be retarded is calculated based on the detected operating conditions of the engine when it is detected that the engine has been recovered from the fuel cut state to the fuel supply state. Further, the ignition timing is corrected based on the calculated retard amount. <IMAGE>
